What is 'rollback' command in perl?
Answer / Biswajit Das
The 'rollback' command in Perl is not a built-in command. However, it is associated with database transactions and can be used to undo all the changes made during a transaction without committing them. In Perl, you would typically use the DBIC (DBIx::Class) or DBD (Database Interface Modules) modules to handle transactions and rollbacks.
